Tail dragging device used for hoisting equipment, tail dragging vehicle and equipment hoisting method

Abstract

The invention discloses a tail dragging device used for hoisting equipment, a tail dragging vehicle provided with same, and an equipment hoisting method for tail dragging through the provided tail dragging vehicle. The tail dragging device comprises a supporting mechanism (200) and a rotating mechanism (300), wherein the rotating mechanism (300) is rotatably and detachably installed on the supporting mechanism (200), and the supporting mechanism (200) comprises a front supporting seat (201); and the rotating mechanism (300) comprises a supporting frame (310), wherein a rotating shaft (301) is installed at the bottom of the supporting frame (310) and supported on the front supporting seat (201), and the supporting frame (310) can rotate between the horizontal position and the vertical position around the rotating shaft, and comprises a first support member (311) mutually matched with equipment (400) for supporting the equipment when the supporting frame is in the vertical position. The tail dragging vehicle comprises the tail dragging device and a travelling mechanism. The provided tail dragging vehicle can save the hoisting cost and has better versatility.

Description

technical field [0001] The present invention relates to the field of auxiliary equipment for hoisting and hoisting of large-scale equipment, in particular to a tail-sliding device for hoisting equipment, a tail-sliding vehicle including the tail-sliding device, and tail-sliding operations using the tail-sliding vehicle provided by the present invention equipment hoisting method. Background technique [0002] With the development of petrochemical technology and the increase of equipment scale, the main equipment is becoming larger and more closely arranged. During the construction process, higher requirements are put forward for equipment installation, and the demand for super-large hoisting tools is increasing. When hoisting large-scale cylindrical equipment (such as tower petrochemical reactors), more than two cranes or cranes and roll-and-slide devices are generally required to work at the same time. At present, there are three main hoisting methods for large cylindrical ...

AI Technical Summary

Problems solved by technology

There are certain defects in the tail-sliding devices currently used. For example, the rated lifting capacity of the crane for tail-sliding needs to exceed half of the weight of the equipment, and the hoisting cost is too high for ultra-large equipment above 1,000 tons; The sliding device needs to be equipped with a special track, so the versatility is not good, and the synchronization between the main crane and the rolling and sliding device is not easy to control
